Uses: Nitrobenzene is an important organic intermediate. Nitrobenzene is sulfonated with sulfur trioxide to obtain m-nitrobenzene sulfonic acid. It can be used as a mild oxidant and anti-dyeing salt S for dye intermediates. Nitrobenzene is sulfonated with chlorosulfonic acid to obtain m-nitrobenzenesulfonyl chloride, which is used as an intermediate for dyes and medicines. Nitrobenzene is chlorinated to obtain m-nitrochlorobenzene, which is widely used in the production of dyes and pesticides, and m-chloroaniline can be obtained after reduction. Used as a dye orange-based GC, and also an intermediate for medicines, pesticides, fluorescent brighteners, organic pigments, etc. Nitrobenzene can be re-nitrated to obtain m-dinitrobenzene, and m-phenylenediamine can be obtained by reduction, which can be used as dye intermediates, epoxy resin curing agents, petroleum additives, cement accelerators, and m-dinitrobenzene is vulcanized. In principle, meta-nitroaniline is also obtained in the sodium proceeding part.
